I think focusing on religion/christianity is missing the point here - it's irrelevant probably, the point is that on global web 2.0 websites there may be manipulation

That's kinda weakness of english language itself, because when everybody is capable of using it, then it's hard to distinguish actual native speakers from foreign actors (and genuine users too) that are proficient at it,

meanwhile let's say that you have group of people only using some not so popular language like X, then it's way harder to pretend to be X user, so at worst you're being trolled by people from your country which may not have as bad intentions.

Or maybe I'm too optimistic about my not so popular language :)
